Our Verdict
Levoit Core 600S
Coway Airmega 400
The Coway Airmega 400 is a better air purifier overall than the Levoit Core 600S, though the Levoit remains a compelling alternative at a much lower price. Both units deliver excellent air-cleaning performance in larger spaces, but the Coway pulls ahead with stronger particle filtration and quieter operation. The Levoit counters with a more modern feature set, including smartphone app connectivity, voice assistant support, scheduling, and remote air quality monitoring, all of which are absent on the Coway.
